VoIP settings
On this screen you configure the ports for establishing VoIP connections.
Settings ¢ Network and Connections ¢ VoIP Settings
"Listen ports" for VoIP connections
¤ Select the ports on which your phone expects incoming VoIP connections.
Use random ports
¤ Select Ye s if the phone should use any available ports for the SIP port and RTP port instead
of fixed ports.
The use of random ports is advisable if you want multiple phones to be operated on the
same router/gateway with NAT. The phones must then use different ports so that the NAT
for the router/gateway is only able to forward incoming calls and voice data to one (the
intended) phone.
¤ If you click on No, the phone uses the ports specified in SIP port and RTP port.
SIP port
Specify the local communication port that the phone should use to send and receive sig-
nalling data. Specify a number between 1024 and 49152. The default port number for SIP
signalling is 5060.
RTP port
Specify the local communication port that the phone should use to receive voice data.
Enter an even number between 1024 and 49152. The port number must not be the same
as the port number in the SIP port field. If you enter an odd number, the next lowest even
number will be selected automatically (e.g., if you enter 5003, then 5002 is set automati-
cally). The default port number for voice transmission is 5004.
ICE enabled
Choose whether or not to use ICE (Interactive Connectivity Establishment). ICE is similar to
STUN (
£ page 111) a Session Initiation Protocol (SIP) method for overcoming NAT fire-
walls.
